Application filed May 5,

This invention relates to radio apparatus, particularly to aerials for the collection of the energy sent out by radio transmitting stations, and has for its object the provision of a novel aerial of peculiar design so con Another object of the invention is to pro vide an aerial which will bring in the desired signals with much greater plainness and distmctness'than is possible under ordinary circumstances.

A further object is to provide a device of this character which, while possessing the advantages above mentioned, is not likely to bring in any more static or interference than is the case with the employment of the usual type of aerial.

An additional object isthe provision of a device of this character which will be simple and inexpensive in manufacture, easy to install or interpose in conjunction with an ordinary aerial, and which will moreover be highly efficient in use, durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction and arrangement of parts to be hereinafter more fully de-.

scribed and claimed, and illustrated in the accompanying drawings, in which 2- Figure l is a side elevation of the device showing it associated with an ordinary aerial.

Figure 2 is a side elevation of the device alone taken on a somewhat larger scale.

Figure 3 is a cross section taken on the line 3-3 of Figure 2.

Figure 4 is a detail view showing the wiring connections, and

Figure 5 is an elevation of one of the elements alone.

Referring more particularly to the drawings, the letter A designates a support which might be a mast or pole ordinarily used tor suspendin a radio aerial wire 13. The letter O designates an insulator connected 1926. Serial No. 106,897.

with another-support D, in the usualfmanner, and which might use from the roof of a house E or other building or support, a

lead-in wire F being connectedwith the wire B at the insulator. C and extendm'g down to a: switch G having a contact H withwliichj connectsa wire 1 leading into the house for connection with a radio set J. The switch is also shown as havinga contact K with which connects a ground wire L for light ning protection when the switch is properly thrown. These details are immaterial but are shown to explain the invention. Connected with the support or mast A by a suit able flexible member M is an 'insulat'orN w'th which, under ordinary circumstances,

the aerial wire B would be connected. However, in the present invention, the aerial wire B is not connected directly with the insulator N inasmuch as the dcviceydesig na'ted generally by the numeral 10 and constituting thesubject matter of this invention is interposed between the insulator N and the aerial wire.

In carrying out the present invention, I have shown the special aerial device designated by the numeral 10, as above mentioned, as comprising a pair of metal disks 11 which may, in actual practice, be conveniently formed of copper coated with tin in order to reduce the likelihood of corrosion under weather influences. Each of these disks 11 is formed with the radial slot 12, the slots in the two disks being reversed so that when the two disks are engaged at the slot they will be in substantially the same relation though arranged atright angles to each other. These disks have their peripheries notched at regularly spaced intervals as indicated at 13, for a purpose to be described.

F or maintaining the disks in their right angularly arranged relation, use is made of a plurality oi brace members 13 which are preferably angular in cross section and welded, soldered, brazed, riveted or otherwise secured to the disks. It is of course apparent that the ends of these brace members are beveled where they engage the disk members 11 so as to provide a proper joint at each place. Obviously, certain of the brace members will be longer than others owing to the fact that the members 11 are or circular shape but this is an immaterial detail and need not be elaborated upon.

Secured to one disk is an arm member 14 which is preferably provided with an eye 15 so that the aerial wire B may be connected therewith.

It is intended that the structure defined by the disks 11 be wound with wire indicated at 16 which will therefore define a substantially rectangular structure as shown in Figure 3. One end of this wire is connected with a suspension wire 17 connected with the insulator N, while the other end 18 is brought through an eye 19 on an arrn, 20

carried by one of the intersecting "disk mem greatly increase the selectivityoif the radio receiving set so that stations from much longer distances, than is ordinarily the case, may be received clearly and distinctly. The exact theory is believedto be immaterial inasmuch as the results are as above mentioned.

It is thought that the advantages as well as the construction and operation will be readily apparent to one skilled in the art without further explanation.

While I have shown and described the preferred embodiment of the invention, it

should be understood that reserve the right to make such changes inthe form, constructionfand arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thns described the invention, I

claim ISA radioreceiving aerial comprising a pair of disks secured together in inteisecting relation and having their peripheries tormed withnotches, and a winding of wire engaged within said notches and trained about the assembled disks. v a

2. A radio receiving aerial comprising a pair of circular plate members mortised together in intersecting relation, and a winding of wire en D atthe edges thereof.

3. An auxiliary radio aerial comprising a pair of circular metal plate members slotted radially and interengaged to extend from each other at right angles, supporting means for the plate members, the ed es of the plate members being provided with notches, and a wire winding about the plate members engaged within the notches, both ends of the wire Winding being connected with the usual radio receiving aerial.
